Abstract

The computer program CZAEM is designed for elementary capture zone analysis, and is based on the analytic element method. CZAEM is applicable to confined and/or unconfined flow in shallow aquifers; the Dupuit-Forchheimer assumption is adopted. CZAEM supports the following analytic elements: uniform flow, uniform infiltration over a circular area, wells, and line-sinks. The line-sinks can be used to simulate streams and the boundaries of lakes and rivers. The program will generate and plot the envelopes of capture zones, the boundaries of capture zones corresponding to different times, dividing streamlines including stagnation points, streamlines, and piezometric contours.
